Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | In this paper, we present the results of calculations aimed at the optical
radiation efficiency of Ag and Au nanoparticles, which is defined by the ratio of the
scattering cross-section to the extinction one. The calculations were performed using Mie
theory formalism for surrounding medium of various refractive indexes. It has been
shown that silver nanoparticles exhibit substantially larger optical efficiency in a broad
spectral range as compared to gold nanoparticles. The optical efficiency for silver
nanoparticles with diameters over 90 nm exceeds 90%. |
